Huashengming compact rock crushers feature dual-roll crushers as their core technology, encompassing spring/hydraulic models, jaw crushers, and double-stage crushers to meet small-to-medium crushing demands. Their advantages include wear resistance for extended service life, precise and controllable particle size, and low maintenance costs. They are particularly suited for sand production and fine crushing of medium-hard materials like river pebbles and granite. Model selection should consider production capacity, material properties, and automation requirements. Standard models offer high cost-effectiveness, while premium hydraulic models better suit continuous intelligent production scenarios.Huashengming offers high-quality, energy-efficient, and environmentally friendly small rock crusher for sale。

Parameters: Feed size 125–350mm, discharge size 10–40mm, capacity 1.2–60 t/h, power 5.5–30 kW.
Two-stage Crusher
Upgraded hammer crusher: Screenless design suitable for wet materials (e.g., coal gangue, granite)
Compact models: 600×600 (20–30 t/h, 22+22 kW), 800×600 (35–55 t/h, 45+55 kW).
2. Performance Advantages and Core Technologies
Wear-Resistant and Durable
Roll shells/jaw plates made of high-chromium manganese steel + rare metals, lifespan ≥2 years, reducing replacement frequency of wear parts.
Precise and Controllable Particle Size
Hydraulic or spring systems adjust clearance (1–50mm), minimizing over-crushing and producing well-rounded finished particles (e.g., uniformly sized river pebble sand).
Energy Efficiency and Environmental Protection
Dual-motor drive reduces energy consumption (30% more efficient than impact crushers) with integrated dust collection systems for minimal emissions.
Intelligent Protection
Hydraulic spring overload protection (automatic roller retraction upon encountering hard objects), supports remote monitoring and fault diagnosis.
High Adaptability
Processes high-moisture materials (dual-stage crusher) and medium-to-high hardness rocks (compressive strength ≤250MPa), such as granite and basalt.
3. Application Scenarios & Model Recommendations
| Application Scenarios | Recommended Models | Features |
|---|---|---|
| Small-scale sand plants (output <20 t/h) | 2PGT400×400、PE-250 | Low investment, compact footprint, ideal for river pebble/limestone sand production |
| Medium-scale production lines (output 20–50 t/h) | 2PGY800×600, Two-stage 800×600 | Hydraulic intelligent control, high efficiency in processing granite/construction waste |
| Wet material crushing (e.g., coal slag) | Two-stage Crusher 600×600 | Screenless design prevents clogging, suitable for high-moisture materials |
| Mobile operation requirements | Custom Diesel-powered Models | No external power required, flexible deployment |
